I came across this option via a craigslist ad (the kayak sold before I could act). It is called Folbot. These are fold up, packable kayaks. It is practical in terms of transportation, but the catch is you are assembling and disassembling the thing from time to time.
Regardless, the video makes them look sweet and I like that they show people fly fishing from them. I would have to buy used because of the price tag. I think that would be fine because they seem to have stood the test of time having been around for years. I saw Nanook of the North in 7th grade, but I never really thought I could purchase the family carrying kayak of the north. Anyway, if I pick one up, I'll be sure to let you know how it goes.
